The e-mail messages that are stored in an Offline Folder file are larger than the e-mail messages that are stored on an Exchange server (817957)
The information in this article applies to:
- Microsoft Office Outlook 2003
SYMPTOMSWhen you view e-mail messages that POP3 users sent to your
Microsoft Exchange Server e-mail account in Outlook 2003, you may find that the
sizes of the message are different depending on whether you are online or
offline. The messages that are stored in an Offline Folder file (.ost) are much larger than the same e-mail messages that are stored on an Exchange server.CAUSEThis problem occurs because the message stores used for
online (.mdb) and offline (.ost) use different properties and attributes
depending on where the messages are located. Differences in the Exchange .mdb
and Outlook .ost database structure may cause the observed difference in
message/folder/mailbox size.MORE INFORMATIONWhen you compare the message size of your .ost file and the
online data you may notice up to 60% difference in message sizes because of
this issue.STATUSMicrosoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
